“…These species are sympatric in at least part of their range (Getz, 1962;Krebs, Keller, & Tamarin, 1969), and interspecies interactions probably do occur between them (Zimmerman, 1965; but see Krebs, 1977). Various studies have indicated that prairie voles and meadow voles display high inter-and intraspecific aggression during staged encounters (Colvin, 1973;Getz, 1962;Miller, 1969).…”

Interactions between congeneric species in sympatry offer opportunities to study mating preferences for conspecifics, preferences that maintain premating reproductive isolation between species. Sixteen males and 16 females of two sympatric species, prairie voles (Microtus ochrogaster) and meadow voles (M pennsylvanicus), were tested for conspecific as opposed to heterospecific preferences in an automated preference apparatus. The results indicated that male prairie and meadow voles displayed preferences for conspecifics when the females were in estrus, but showed no preference when females were in diestrus. Female prairie voles in both estrous and diestrous conditions likewise displayed a preference for conspecifics, whereas meadow vole females showed no such preference. These species differences may be related to social organization, for prairie voles are monogamous, pair-bonding, and contact-prone, whereas meadow voles, which are polygamous, display high intraspecific aggression during initial contact. Conspecific preferences can be considered as one factor that maintains existing isolation between the species.Interactions between congeneric species in sympatry offer opportunities to study the factors that maintain premating reproductive isolation between those species. The discrimination of and mating preferences for conspecifics constitute one such factor. This study was designed to investigate conspecific preferences in two sympatric species of voles, prairie voles (Microtus ochrogaster) and meadow voles (M. pennsylvanicus).For sympatric species, the ability to discriminate conspecifics from heterospecifics is important for such reasons as the selection of a mating partner and the exclusion of potential resource competitors. As one might expect, the species tested have generally shown a preference for conspecifics over members of closely related species. In two-choice preference tests, male preferences for female conspecifics have been demonstrated in several species of mice of the genus Peromyscus (Bradshaw, 1965;Moore, 1965;Smith, 1965). Murphy (1977) reported that females of three hamster species displayed preferences for conspecific males. Turkish hamsters, the species with the greatest sympatric overlap, showed the strongest conspecific preference (Murphy, 1977(Murphy, , 1978. Preferences for conspecific odors or avoidance of heterospecific odors have been noted for several vole species, including male Microtus califomicus (Heske & Repp, 1986), M. pennsylvanicus (McGuire & Novak, 1987), M. agrestis, and Clethrionomys glareolus (de longe,

“…In a study focusing on the feeding preferences of the prairie vole (Microtus ochrogaster Wagner), S. faberi seed were preferentially chosen by the voles even though this foxtail species was not common in the study area (Pascarella and Gaines 1991). This finding was supported by Zimmerman (1965), who showed that prairie vole populations in Indiana preferentially chose S. faberi seeds as a food source even though the seeds only accounted for 1.4% of their diet. Haken and Batzli (1996) found that S. faberi seeds were the lowest ranking food choice for the prairie vole, while the S. faberi seeds were not chosen at all by the meadow vole in Illinois.…”

known as giant foxtail, is an annual graminaceous weed that is native to eastern China, has colonized eastern North America and is expanding its range westward. This species is primarily self-pollinated and the only mechanism of reproduction is by seed. Adult plants may reach 2 m in height and produce over 2000 seeds per panicle. Seeds may possess non-deep physiological dormancy when freshly produced, and can form small persistent seed banks. If not controlled, S. faberi populations can cause severe yield reductions in corn and soybean crops. Several herbicides are available to provide chemical control; however, resistance to some modes of action, (ALS, ACCase, and Photosystem II) have been identified in Canada and the United States. Leaves and seeds of this species provide a food source to several species of mammals, birds, and insects.

“…It is an important component in the diet of at least two voles with broad distributions in North America, Microtus pennsylvanicus Ord and M. ochrogaster Wagner (Zimmerman 1965). Weaver and Albertson (1944) referred to P. capillare as an important ground cover under drought conditions in Kansas.…”

[327][328][329][330][331][332][333][334][335][336][337][338][339][340][341]. Panicum capillare L., witch grass, is an annual grass native to North America that infests field crops, small grains, grasslands, and a variety of other habitats. High seed production, a persistent seed bank, a tumble-weed seed-dispersing mechanism, and the ability to tolerate some herbicides contribute to the success of P. capillare in these habitats. Despite the widespread presence of P. capillare in crops, its actual impact on crop yield is not well documented. It is an additional host for several insect pests (e.g., cereal aphids) and diseases attacking crop species.
